The use of background images enables you to handle the « JS enabled but broken » case, which current polyfills such as picturefill fail at.</p> <p>A few comments :<br class="autobr" /> * Using background-images as the final image displayed has the downside of mixing content-images into the CSS, which can cause maintenance and caching issues. That's something that should be taken into consideration. The impact can be reduced by separating these background images into their own external CSS.<br class="autobr" /> * Bandwidth measurements are extremely inaccurate, and should be taken with a grain of salt. I completely agree that active BW measurements are actively harmful, but even passive ones are problematic, since you consider the results thinking that you know what the network's state is, and there's a good chance that you don't.<br class="autobr" /> Looking at the bandwidth measurement code, it seems rather racy. The value for responseEnd is not known before the HTML has finished downloading, so with large HTML files, you might miscalculate it. <br class="autobr" /> * Data URIing the low quality image can be beneficial (less requests), but can also have a negative impact, by adding non-blocking resources into the critical path. So it's probably a good idea to measure the impact of data URIs vs. external resources here, and in some cases, opt for external resources.</p> <i lang="en">Adaptive Images</i> et Responsive Web Design 2013-11-16T13:07:44Z https://blog.nursit.net/Adaptive-Images-et-Responsive-Web.html#comment267 2013-11-16T13:07:44Z <p>Hello,</p> <p>Voila un tuto bienvenu pour optimiser les images en fonction des terminaux. La demande croissante en responsive design liée à l'explosion du trafic mobile nécessite d'inventer de nouvelles techniques, c'est passionnant.</p> <p>Mary, graphiste chez Sublimeo</p>
